Hi

I have a cisco AP 3602I which was working fine with WLC. I download new firmware to WLC and all my other AP’s updated successfully with image from WLC about 30 AP’s.

But one AP did not update firmware it gives an error cannot create directory in flash when I connect with console cable to AP.

So I formatted the flash in rommon mode successfully and I run command flash_init but it says the flash is already initialized. When I tried to download image from tftp I get error please see attached screen shot.

Any advice to get AP up and running again.

Try doing it the TFTP recovery way instead...

- Rename the file to ap3g2-k9w7-tar.default and save it in the TFTP server folder.

- Give your PC IP 10.0.0.2/255.255.255.224 (make sure you're on the same VLAN as the AP).

- Power down the AP, then hold the MODE button and power up the AP, still holding the MODE button in.

- Keep the MODE button held in for at least 30s, then release.


The AP should try to download the image file.  If it does, let it do its thing.  It'll boot automatically.

The image shows you only pressed the button for ~20s.

If you get to the ap: prompt, then do a flash_init then fsck flash: or format flash: you should be able to do the recovery.

Ok, so format the FLASH: first, then try again.

If the Update folder is present the AP can't create a folder called 'Update' (as it already exists) so the upgrade fails.  This is pretty poor coding in my opinion but that's the way it works :-/

Did you try to do a FSCK?  If you have tried that and it still fails there is probably a problem with the FLASH:

That command will do a file-system check.  What errors does it give you?
